Notes:
1. Minimum DC voltage on input or I/O pins is –0.5 V. During voltage transitions,
input or I/O pins may overshoot VSS to –2.0 V for periods of up to 20 ns. See
Figure 7. Maximum DC voltage on input or I/O pins is VCC +0.5 V. During voltage transitions, input or I/O pins may overshoot to VCC +2.0 V for periods up to 20
ns. See Figure 8.
2. Minimum DC input voltage on pins A9, OE#, and RESET# is -0.5 V. During
voltage transitions, A9, OE#, and RESET# may overshoot VSS to –2.0 V for
periods of up to 20 ns. See Figure 7. Maximum DC input voltage on pin A9 is
+12.5 V which may overshoot to 14.0 V for periods up to 20 ns.
3. No more than one output may be shorted to ground at a time. Duration of the
short circuit should not be greater than one second.
Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational sections of this data sheet is not implied. Exposure of the device to absolute maximum rating conditions for extended periods may affect device reliability.OPERATING RANGES
